Two suns over Tatooine?
06/27/08 12:14 , Categories: Science in SF Continuing in the search for a suitable star for a science-fictional planet to call home... It's widely known that many stars are found in pairs, in which one star orbits around the other. The idea of having not one sun, but two, has fascinated many people. But one must tread fairly cautiously if one wants to create such a system.
Would you like to swing 'round a star?
06/23/08 11:08 , Categories: Science in SF Continuing along earlier lines of constructing your very own habitable planet for science-fictional purposes, it's useful to consider what type of star you want to build your "solar system" around. (More accurately, "stellar system", since solar refers to our own sun.)
For the purposes of this discussion we'll stick to "adult" stars - stars that are on what astronomers call the main sequence. Older stars which leave the main sequence may puff up into "giant" or "supergiant" stars for a while, but these stages tend to last for only a tenth or so of the star's lifetime - the remaining nine-tenths are on the main sequence. So we'll set aside, for example, red giant stars for another discussion.
